Question by seb-lopez · Aug 03, 2014 at 02:25 PM · nullreferenceexception

NullReferenceException: Object reference not set to an instance of an object.

in my script i get a NullReferenceException: Object reference not set to an instance of an object dangerzone.Awake () (at Assets/Levelkit 1/FPSScripts/dangerzone.js:5). the script is a trigger box collider that when it hit the player it will take you 5 point of life .the script works fine but i always see this error and i suspect that it my be the reasons why my game lags

here is my script:

 #pragma strict
 var healthScript : healthscriptforplayer ;
 var animator: Animator;
 function Awake () {
  healthScript = GameObject.Find("First Person Controller ").GetComponent( healthscriptforplayer  );
 }
 
 function OnTriggerEnter (Col : Collider ) {
 if ( Col.tag == "Player"){
     animator.SetBool ("Nattack" , true);
     animator.SetBool("Nwalk" , false);
     healthScript. CurrentHealth -= 5;
 }
 }
 function OnTriggerExit (Col : Collider ) {
 if ( Col.tag == "Player"){
     animator.SetBool ("Nattack" , false);
    
 }
 }

please help.

Try changing

 function Awake () {
 healthScript = GameObject.Find("First Person Controller ").GetComponent( healthscriptforplayer );
 }

to

 function Start() {
 healthScript = GameObject.Find("First Person Controller").GetComponent( healthscriptforplayer );
 }

Are you setting healthScript in the inspector? If so, you shouldn't need to perform a lookup.

Anyhow, if GameObject.Find returns null, that means no GameObject with that exact name exists at that exact time.

In the Awake() function some of the game objects in the scene may not exist yet. It is better to look for your "First Pereson Controller" in the Start() function.
